Aircraft antenna fairing assemblies (20) include a fairing shell (30) and connection components (60, 70, 80, 90) for positionally fixing the fairing shell to airframe structure of an aircraft (10). The connection components comprise a guide assembly (60, 70) having a guide head (62b, 74b) and a receiver (64, 78) defining a guide channel for receiving the guide head therewithin, and a latch assembly (90) for latching the fairing shell to the airframe structure of the aircraft. The receiver of the guide assembly defines a generally C-shaped or generally U-shaped channel for receiving the guide head therewithin.

Systems are disclosed to allow for the landing gear doors to be opened in the event of an emergency gravity free-fall landing gear deployment with little or no contact with the landing gear tires. The emergency gear extension systems according to the embodiments disclosed herein thus permit the free-fall movement of the landing gear to be synchronized with the opening of the associated gear doors. That is, according to the embodiments disclosed herein deployment of the landing gear assembly is time-delayed relative to the opening of the associated gear door(s). In such a manner, the landing gear assembly is synchronously released only after the associated gear door is in a safe position during its opening sequence thereby avoiding the risk that the gear door will jam the full extension of the landing gear during an emergency gear deployment due to contact between the landing gear tires and the gear door.

Assemblies and methods for the handling, transporting and/or positioning component parts include a jig assembly for supporting a component part is provided with an elongate spar assembly, a plurality of rib assemblies attached to the spar, and a plurality of tensionable strap assemblies operatively associated with the rib assemblies for capturing and holding the component part against the rib assemblies. The strap assemblies may include a strap ratchet mechanism and a strap, so that operation of the strap ratchet mechanism allows strap slack to be removed thereby tensioning the strap. The jig assembly may be positioned and oriented by suspension cables and a hoist mechanism to allow it to be removably connected to a moveable transport dolly.

Passenger interface units include individual passenger modules (14a,14b) having co-located controls for passenger comfort and entertainment systems. The modules (14a,14b) will include a glass panel (40) having front and rear surfaces, a structural support panel (42) bonded to the rear surface of the glass panel (40) and a light-emitting unit (50) supported by the support panel (42) behind the rear surface of the glass panel (40). The rear surface of the glass panel (40) may include an opaque printed coating layer (46) having at least one unpainted region that is transparent to visible light emitted by the light-emitting unit (50) thereby allowing the visible light to be transmitted through the glass panel (40) and visible at the front surface thereof.

Structural analysis automation allows the implementation of more detailed or accurate analysis methodology that reflects the actual behavior of the damaged or repaired structure and consequently improves the resulting damage disposition for example by Increasing the allowable damages and structural repairs applicability, increasing the allowable damage limits causing the reduction of unnecessary installation of structural repairs, optimizing repairs and increasing fly-by periods and inspection intervals.
